Long Island City, N. Y., a corporation of New York Application April 24, 1946, Serial No. 664,540 8 Claims. (Cl. 164-411) The subject matter of this invention is a perforating device wherein movably guided punch means is adapted to be actuated for desirably punching relatively light and heavy sheets of paper either singly or in stacks thereof. The object of the invention is realized in the provision of novel stabilized and telescopically associated means for self centering the sheets on the base of the perforating device prior to the punching operation. Specifically another object of the invention is to provide a self-centering gage comprising superimposed and spaced bars slidably guided widthwise of the base and having facing but spaced rack means coacting with an intervening rotatable pinion common to the spaced rack means and carried by a bracket or support concealed from view and sustained within the base of the perforating device. A further object is concerned with an improved self centering gage having spaced and superimposed gage bars movable in unison towards or away from each other and adapted to conveniently straddle a sheet of paper or a stack thereof on the base of a perforating device to properly position or self center the sheets of paper or stack relative to the punch means prior to perforating of the paper or stack. A further object is to preclude outward separation of the superimposed and slidably guided gage bars. Another object has to' do with removably telescoping the superimposed and slidably guided gage bars to stabilize the latter. Other important objects and advantages will appear from the accompanying drawings taken with the following detailed specification wherein:

Fig. 1 is a perspective view of the perforating device according to my invention, illustrating the self centering gage.

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1 showing one of the fixed guides for a companion slidable punch.

Fig. 3 is a fragmentary view of Fig. 1.

Fig. 4 is a vertical sectional view on the line 4-4 of Fig. 1.

Fig. 5 is a fragmentary enlarged and broken view of Fig. 4, showing the gage bars in an interlocking relation.

Fig. 6 is a sectional view on the line l--' of Fig. 5 and Fig. 7 is a perspective view of the bracket or rack housing.

The perforating device is broadly denoted II and comprises a base Ii and spaced stanchions l2 appropriately fixed to the base and each housing a fixed loop shaped bearing If for slidably guiding a punching tool T carried by a u-shaped tool lifting member it and in part enclosing bearing i5 surrounding pin it slidably guided in the spaced cam slots il in the spaced side walls of a stanchion which carries the fulcrum pin it to which a pair of depending portions or ears It of the handle H is pivotally retained. Although pins it are movably guided in the spaced cam slots ll of the stanchions they are carried by the depending ears i9. Consequently if the handle H is pivoted, pins it are actuated to shift slidably guided tool lifting members ll to raise or lower the punch means '1' in the spaced stanchions. surrounding each fulcrum pin it is a coiled spring having a free end 2i abutting the handle and having another end retained against an offset lug 23 secured to a stanchion. The foregoing structure is more. fully described in United States Letters Patent to Calvin P. Kipp Patent No. 2,328,558, issued September 7, 1943, and is merely set out herein to disclose the relationship of the self centering gage broadly designated G and the spaced punching punches or tools '1 slidably guided in the spaced and fixed bearings It. The

gage G comprises superimposed, vertically spaced and slidably guided gage bars 25 and 28 each having an upstanding or manipulator lug 21 either of which may be grasped and actuated for automatically shifting the bars either towards or away from each other. If the gage bars move towards each other the manipulators 21 straddle the sheets of paper or stock (not shown) on the base and centers the sheets relative to the punch means.

More specifically, each of the gage bars is provided with a plurality of teeth 28 defining rack means meshing with a toothed pinion 29 fixed to shaft 20 journalled in or rotatably carried by the spaced sides iii of a bracket or support B having diagonally disposed but laterally extending wings 32 appropriately secured by screws 33 to the base II. The bracket B may be considered as a one piece channeled shaped member or housing having the bottom wall 34 from which the sides 3| project in parallelism.

The base ii also embodies depending sides 35 having the horizontally alined but vertically spaced openings 36 and 31 for slidably guiding the lower and upper gage bars 26 and 25 also slidably retained between the parallel sides ll of the bracket B.

By the present arrangement, if one of the manipulators 21 is controlled to slidably shift its gage bar, the, other gage bar is correspondingly displaced but in an opposite direction. Fbr example, if an outward thrust be applied to the manipulator 21 of the upper gage bar, the latter is projected outwardly a certain distance and of course the pinion 29 is rotated, thus causing displacement of the lower gage bar in an outward direction and to a distance equal to the outward displacement of the upper gage bar. The coaction of the rotatable pinion with the upper and lower racks causes these bars to move in unison at all times. Consequently, if an inward thrust be applied to either of the manipulators each of the guide bars is projected an equal distance into the base. Conversely if either of the manipuiators has applied thereto an outwardly directed thrust, the gage bars as previously stated are slidably displaced an equal distance but outwardly relative to the base. If therefore a sheet of paper or a stack of sheets (not shown) he placed on the base and if the manipulators be brought towards the sides of the paper or stack thereof, the latter will be automatically centered relative to the spaced punches or cutting or perforating tools '1 slidably guided in the fixed spaced stanchions it.

With the sheets of paper or stack wntered, the handle H is pivoted downwardly to direct the punches to perforate the paper or stack. Upon removal of manual pressure from the handle, the latter elevates automatically due to the action of the free ends 2i of the coiled springs 20, thus raising the cutting tools T from the perforated and spaced anvils A fastened to the base I I.

The bottom wall 34 of the bracket is provided with an upstanding lug or stop 38 projecting into the elongated longitudinally arranged slot or gap 39 in the slidably guided and lower gage bar 26, lug 38 cooperating with the ends of slot as to limit displacement of the gage bars towards or away from each other. Lug 3d and slot 39 also provide suitable interlocking means to preclude involuntary disconnection of the lower rack from the pinion.

Manipulator 2'! of the lower gage bar 26 is slightly longer than the manipulator 21 of the upper gage bar so that terminals 40 thereoi are at the same elevation. The manipulator of the lower gage bar also embodies a suitable slot M for slidably receiving and interlocking with the free end 42 of the upper case bar. Hence when the manipulators straddle a narrow sheet of paper or narrow stack to be perforated, the gage bars may be said to be telescoped, and such action stabilizes these bars.

- By the present invention, the gage bars may be quickly assembled with the base i i and the bracket B and in this connection, the latter is first fastened to the base after which the superimposed gage bars are projected into the slots 35 and lit vils A to provide the gaps to permit insertion of a sheet of paper or stack thereof under the guides i3, which include the superimposed legs 5i (Fig. 2) positioned on the bottom wall 52 of the stan chions l2 and the latter on the spacer means to of the base H, and spaced rivets 54 secure legs 5! of the guides i3 to the bottom wall 52 of the stanchions and the latter to the spacer means 63.

Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificlng any of the advantages thereof inherent therein.

Subsequently ing 38 is bent to project into slot 39 in the lower gage bar, thus precluding separation of the gage bars from the fixed bracket B desirably concealed within the depending-rim 43 of the base of which the spaced sides 35 are a part.

It should be understood that the U-shaped yokes or tool lifting members It are reciprocated in the stanchions l2 when the pivoted handle H is depressed and raised. Thus on the downward stroke of the handle, the spaced tools T are forced through the paper or stack and through the perforated anvils A, thus piercing or punching the paper or stack. Pursuant to such operation, the pivoted handle automatically retracts due to the restoring action of spring terminals 2i and consequently the spaced tools T retract into the guide i3.
